Abstract

Introduction: This study evaluated the relationship between relative handgrip strenght index (rHGSi) as well as chronotropic response index (Cri) and heart rate recovery index (HRRi), which are the prognostic parameters of treadmill exercise.

Patients and Methods: In total, 490 patients who were recommended to undergo the exercise electrocardiographic test were recruited in this study. The participants were divided into two groups based on both Cri (normal and low CRi groups) and rHGSi (high and low rHGSi groups).

Results: The treadmill exercise time, peak heart rate, and metabolic equivalents were higher in the high rHGSi group than in the low rHGSi group. In addition, the 1st minute HRRi and Cri were higher in the high rHGSi group than in the low rHGSi group. The treadmill exercise time, basal and peak heart rate, metabolic equivalents, and 1st minute HRRi were significantly lower in the low CRi group than in the normal Cri group. rHGSi was considered an independent predictor of low chronotropic response index. Based on a bivariate analysis, a statistically significant positive correlation was observed between Cri and rHGSi. Similarly, there was a positive association between rHGSi and 1st minute HRRi.

Conclusion: rHGSi might be a practical and effective tool in cardiovascular risk stratification.

Rölatif El Kavrama Gücü İndeksi ile Kronotropik Cevap İndeksi ve Kalp Hızı Toparlanma İndeksi İlişkili mi?

Abstract

Giriş: Bu çalışmada, rölatif el kavrama gücü indeksi ile egzersiz testinin önemli prognostik belirteçleri olan kronotropik cevap indeksi ve kalp hızı toparlanma indeksi arasındaki ilişki araştırılmıştır.

Hastalar ve Yöntem: Treadmill egzersiz testi planlanan 490 hasta çalışmaya alındı. Çalışma grubu el kavrama gücü indeksi ve kronotropik cevap indeksi değerlerine göre ayrı ayrı ikişer gruba ayrıldı.

Bulgular: Yüksek rölatif el kavrama gücü indeksi grubunda, treadmill egzersiz zamanı, zirve kalp hızı ve metabolik ekivalan değeri düşük rölatif el kavrama gücü indeksi gruba kıyasla daha yüksek bulunmuştur. Ek olarak kronotropik cevap indeksi ve birinci dakika kalp hızı toparlanma indeksi gibi prognostik parametreler de yüksek rölatif el kavrama gücü indeksi grubunda daha yüksek bulunmuştur. Çalışma grubunu kronotropik cevap indeksine göre gruplandırıp incelediğimizde, treadmill egzersiz zamanı, bazal ve zirve kalp hızı, metabolik ekivalan ve birinci dakika ve kalp hızı toparlanma indeksi değerleri düşük kronotropik cevap indeksi grubunda yüksek kronotropik cevap indeksi gruba kıyasla daha düşük tespit edilmiştir. Ek olarak, rölatif el kavrama gücü indeksi düşük kronotropik cevap indeksinin bağımsız öngörücüsü olarak saptanmıştır. Yapılan çalışmada kronotropik cevap indeksi ve rölatif el kavrama gücü indeksi arasında pozitif korelasyon saptanmıştır. Aynı şekilde birinci dakika kalp hızı toparlanma indeksi ve rölatif el kavrama gücü indeksi arasında da istatistiksel olarak anlamlı derecede korelasyon saptanmıştır.

Sonuç: Rölatif el kavrama gücü indeksi popülasyonda kardiyovasküler risk sınıflandırması için kullanışlı ve pratik bir araçtır.
